Overview
Evaluate frequency of adverse events that lead to chemotherapy discontinuation in vulnerable older adults with recurrent/metastatic PD-L1 TPS<50% NSCLC patients who receive reduced dose chemotherapy in combination with immunotherapy.
Description
This is a single institution, single arm, open label phase 2 study in vulnerable or older adults (Age ≥70) with recurrent or metastatic, histologically confirmed squamous cell carcinoma or non-squamous cell carcinoma of lung without driver mutation and PD-L1 TPS < 50% to evaluate safety and tolerability of reduced dose of chemotherapy and immunotherapy.
Eligibility
Inclusion Criteria:

- Stage IV disease OR have recurrent disease and not be candidates for curative treatment such as combined chemo-radiation
- No previous line of treatment in the recurrent or metastatic setting. Neoadjuvant or adjuvant treatment more than 6 months before enrollment is acceptable.
- Age 70 or meeting frailty definition or above at the date of signing informed consent
- Absence of driver mutations that have first line Food and Drug Administration (FDA) approved targeted therapy
- PD-L1 tumor proportion score (TPS) of less than 50%
- Eastern Cooperative Oncology Group (ECOG) PS of 0-3
- Have measurable disease based on RECIST 1.1 as determined by the local site investigator/radiology assessment
- Absolute neutrophil count (ANC) ≥ 1,000/μL
- Platelets ≥ 75,000/μL
- Hemoglobin (Hgb) ≥ 8.0 g/dL (transfusion permitted)
- Total bilirubin ≤ 2 x institutional upper limit of normal (ULN)
- Aspartate amino transferase (AST)serum glutamic-oxaloacetic transaminase (SGOT) /alanine aminotransferase (ALT)serum glutamic-pyruvic transaminase (SGPT) ≤ 5.0 × institutional ULN
- Ability to understand and the willingness to sign a written informed consent document

- Diagnosis of interstitial lung disease
- Creatinine clearance of <30 mL/min
- Symptomatic, untreated central nervous system (CNS) disease or leptomeningeal disease. Patients with asymptomatic or treated CNS disease are eligible
- Required ongoing use of immunosuppressive medication, including steroids, with the
following allowable exceptions:
